![]() ![]() More than 80% of patients showed an impairment in two or more cognitive domains of the OCS. Results: About a third of patients (35.3%) had a performance lower than the cutoff (<22) on the MMSE, whereas 91.6% were impaired in at least one OCS domain, indicating higher incidences of impairment for the OCS. The OCS and MMSE, as well as the Bamford classification and NIHSS, were given according to standard procedures. Methods: 325 first stroke patients were consecutively enrolled in the study over a 9-month period. We further aimed to examine performance on the OCS as a function of subtypes of cerebral infarction and clinical severity. Objective: The present study compared the OCS with the MMSE with regards to their ability to detect cognitive impairments post-stroke. As such, it may have a greater potential to be informative on stroke cognitive deficits of widely used instruments, such as the Mini-Mental State Examination (MMSE) or the Montreal Cognitive Assessment, which were originally devised for demented patients. OCS was devised to be inclusive and un-confounded by aphasia and neglect. ![]() The scale consists of 10 tasks encompassing five cognitive domains: attention and executive function, language, memory, number processing, and praxis.
